Hey!

blkid was added as an applet in busybox. This makes it available in initramfs in
place of the one from util-linux. This prevents cryptsetup to works as the
syntax used is not recognized by busybox.

 10:58 ❱ blkid -l -t UUID=255e21df-9261-47b5-ac37-b4ae4c435a37 -o device
/dev/nvme0n1p3
 10:59 ❱ busybox blkid -l -t UUID=255e21df-9261-47b5-ac37-b4ae4c435a37 -o device
 10:59 ❱ sudo busybox blkid -l -t UUID=255e21df-9261-47b5-ac37-b4ae4c435a37 -o device

cryptsetup-initramfs could parse the output of busybox blkid, but this seems
more fragile. It seems easiest to not ship blkid in busybox (hence the bug
against busybox).

Version: 1:1.35.0-4

busybox (1:1.35.0-4) unstable; urgency=medium

   * static build: disable blkid applet (CONFIG_BLKID, #1023501)

     Since static build has CONFIG_FEATURE_PREFER_APPLETS=y, enabling
     any utility which is also provided by the system in other ways
     can be risky, since busybox shell will choose its applet version
     instead of running the actual utility, even if that utility file
     exists in $PATH. After enabling blkid, we effectively overwrote
     blkid from libblkid as used in initramfs. The result was non-
     working udev rules for block devices (not creating /dev/disk/by-*/),
     and the system's unbootable.

     Disable it for now at least on static build.
     Closes: 1023501

(note the missing # before the bug number).

Lets close this now.
